The invention discloses an electromagnetic turnout device, which comprises an electromagnetic module; the electromagnetic module is within a preset range of a turnout section in a vacuum pipeline, arranged on the inner side wall of the vacuum pipeline, and is used for generating electromagnetic attraction force to a vehicle-mounted induction plate (2) arranged on a train when current is increasedto a set range after electrifying under the condition that the train in the vacuum pipeline needs to be steered, so that the train is steered and switched to a target branch line in the turnout section; the turnout section is positioned at the joint of a main line and a branch line in the vacuum pipeline; and the vehicle-mounted induction plate (2) is arranged on the traveling mechanism of the train. According to the scheme, the problem of complex structure of a mechanical turnout can be solved, and the effect of simplifying the turnout structure is achieved.
